Currently working on customizing a WordPress website. Within my main document, I have the code set up for the header and footer, with a div in between for displaying content. My goal is to have the ability to show content from navigation links clicked within this main content div. If there are any alternative solutions to achieve this, please share your insights. One major challenge I'm facing is preventing the header and footer from overlapping the content. The method I'm using might not be standard for loading pages. Can anyone suggest how I can load other pages while keeping the header and footer in place without them overlapping the content?
